STAMP-CANCELER.

SPECIFICATION forming part of Letters Patent No. 248,45i8, dated October 187 1881. Application filed May 2, 1881. (Model.)

.To all whom it may concern Be it known that I, FREEMAN HANSON, of Hollis, in the county of York and State of Maine, have invented certain new and useful Improvements in Stamp-Cancelers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a sectional view of the device. Fig. 2 is a view of the outer sleeve. Fig. 3 is a view of the inner sleeve. Fig. 4 is a view of the erasing -rod, with the spiral spring, disk, and' pin. Fig. 5 is a view of the bottom end of the outer sleeve, Fig. 2. Fig. 6 is a view of the lower end of the erasing-rod.

Same letters show like parts.

My invention relates to devices for erasing or canceling stamps, Src., and belongs to that class of such implements whereby a portion of the paper of the stamp is cut away by the operation and use of the eraser.

The invention consists in the combination of an outer shell, an outer and inner sleeve, an erasing-rod, a spiral spring, and certain minor devices connected with these main portions, which will be hereinafter described.

a shows the outer shell, forming a handle, and having the screw b to hold theinner sleeve in place.

o is the inner sleeve, and d is the outer sleeve.

eis the stamping or erasing rod. fis the spiral spring coiled around it.

g is a disk moving up and down on the rod.

h is a pin, to work in the spiral slott' in order to give a rotary motion on its axis to the stamping or erasing rod c.

When the implement is used to erase a stamp the shell a is pushed down over theinner parts. The shell is held in the hand, and a blow is struck upon the stamp to be erased by the end, Fig. 6, ofthe erasing-rod e. This blow by its force slips the outer shell, a,down

over the lower end of the outer sleeve, Fig. 2, thereby imparting a rotating motion to the rod c, in consequence of which the stamp is out out by the action upon it of Acertain projecting cutting' points or edges on the lower end of the erasing-rod c. These ed ges are illustrated in Figs. 4 and 6.

Within the shell c is placed the sleeve c, which I have called the inner sleeve.77 Itis held by the screw b. When the shell a is forced downward by the blow before mentioned it carries down with it the inner sleeve, c. The lower end,j, of the inner sleeve rests on the disk g. The upper end of the spiral spring j' rests against this disk and its lower end against the shoulder r. Pushing down the disk, therefore, contracts the spring. When the force of the blow is gone, or ceases, then the elastic power of the spring will push the shell a back to its original position, which is such that the lower end of the sleeve d and of the erasing-rod e project a short distance below it, as illustrated in Fig. l. When thc shell a is thus pushed down, as above described, and with it the inner sleeve, c, the pin h moves in the spirally-eut slot i. This gives the rotary motion on its own axis to the erasing-rod c. The inner sleeve, c, slides down within the outer sleeve, cl. A straight slot, Z, is made in the outer sleeve, d, to receive a pin, m, projecting from the inner sleeve, c, and admit of its motion up and down as the shell is forced downwardly by the blow mentioned and back by the spiral springf. This pin also prevents the inner sleeve, o, from being turned around by the action of the pin lt in the slot z'. A hole, n, in the inner sleeve, c, is for the recep tion of this pin. As theshell a is forced upwardly or downwardly the outer sleeve, d, moves in the annular space o, or an annular space between the inner sleeve, c, and the interior periphery of the shell a.

p is a channel cut around the stamping or erasing rod e to receive two pins, q q', projecting from the interior of the outer sleeve, d, to hold the sleeve and rod in proper relative po* sitions, and at the same time to admit of the rotary motions of the stamping or erasing rod c.

l r is a groove cut around on the bottom end of the outer sleeve, d, into which sponge or UNITED STATES PATENT OFFICE.
